Title

Analysis And Design Of Soft-Switching Power Factor Correction Converter

Abstract

A single-stage power factor correction converter with soft-switching is proposed in this paper. The topology of this converter is derived by adding a resonant circuit to an existing Single-Stage, Single-Switch Power Factor Correction (S4 PFC) converter. As a result, zero-voltage-switching and zero-current-switching are achieved for the main switch and the auxiliary switch, respectively. High frequency operation of the proposed converter makes the ac-dc power supply possible to be minimized in size and weight. The proposed converter uses a grounded auxiliary switch so that the isolated driving circuit is not required. The simplified driving circuitry will again improve the overall efficiency and power density. Practically, the direct driving schemes of both the main and the auxiliary switches will allow the proposed converter to operate in even high switching frequency and have good regulation capability.
